High-Performance PP film extrusion laminating line

A PP film extrusion laminating line is a specialized production system,used to manufacture laminated films by extruding polypropylene (PP) and bonding it to one or more substrate materials (such as fabrics, nonwovens, aluminum foil, or other plastic films).This process enhances the material's properties, including strength, barrier resistance, and durability.

Here’s a professional breakdown:

PP film extrusion laminating line purpose

Combines PP film with base materials such as paper, woven fabric, nonwoven fabric, aluminum foil, or BOPP film.Improves barrier properties (moisture, grease, chemicals), mechanical strength, and printability.

PP film extrusion laminating line Main Components

1.Unwinder(s) – Feeds base materials into the line.

2.Extruder – Melts PP resin pellets into a molten film.

Extruder

3.Die/Extrusion T-die – Spreads molten PP evenly over the substrate.

4.Chill roll unit – Rapidly cools and solidifies the PP film.

5.Laminating station – Presses layers together under controlled temperature and pressure.

6.Rewinder – Rolls the laminated material for downstream processing.

PP film extrusion laminating line Process Flow

1.Substrate feeding → 2. PP resin melting & extrusion → 3. Molten film coating → 4. Cooling & solidifying → 5. Laminating → 6. Rewinding.
